摘要
从UPFC控制潮流的基本原理出发 ,详细地讨论了它对线路潮流的调节情况 ,建立了利用UPFC控制潮流的 3种优化模型 ,并针对UPFC对潮流的控制受功角变化的影响较大的特点 ,提出了一种有效的分段潮流控制策略 :根据暂态过程的不同阶段 ,相应地改变UPFC的控制方式 ,从而可大幅度地改善系统的暂态稳定性。单机无穷大系统的暂态仿真结果表明 :分段潮流控制策略是有效的。
This paper discusses the property of UPFC adjusting power flow and designs three kinds of optimal models. An effective subsection control strategy is proposed based on the characteristics which the range of UPFC control power flow is affected by the change of power angle. With this strategy, UPFC's working modes may vary according to different stage of system transient process, so system's transient stability can be improved greatly. it's effectiveness is illustrated by simulation on a one machine infinite bus system.
